Description

retraction device

The invention relates to a feeder, in particular for drawers, sliding doors, hinged doors, etc. with a spring acted upon by a coupling piece, which is adjustable between a retraction position and a raised position.

The invention further relates to a method for operating a drawer.

From DE 10 2007 008 688 A1 a collection device for drawers is known. This has as a coupling piece on a tilting segment, which is movable when opening a drawer against the bias of a spring from a retraction position to a raised position. The tilting segment is moved by a driver, which is mounted on the drawer side. When the tilting segment has reached the deployed position, the driver is released and the drawer can be pulled out further in the freewheel, uninfluenced by the intake device. When the drawer is closed again, it can be freewheeled until the catch is caught by the tilting pad. Then the previously tensioned spring pulls the drawer into the closed position. In order to prevent a hard impact of the drawer, the retraction movement is braked with a damper.

Increasingly, handleless drawers are desired for design reasons. With the known collection devices such drawers can not always be easily opened, since the drawer is held under the action of the spring in the closed position.

It is an object of the invention to improve the ease of use in a drawer or the like sliding element.

This object is achieved in that a Ausschiebeanordnung can be coupled directly or indirectly with the coupling piece, and that a sliding piece of the Ausschiebeanordnung upon actuation of the Ausschiebeanordnung is adjustable. By means of the Ausschiebeanordnung the drawer can be moved from the closed position into a part-opening position. In this case, the sliding piece is effective, which adjusts the drawer. The partially opened drawer can then be grasped, for example, on the front panel and pulled into the open position.

In this arrangement, a controlled closing movement can be achieved in that a damper dampens the movement of the coupling piece from the raised position to the retracted position.

A preferred embodiment variant of the invention may be characterized in that the coupling piece is held in the parking position by means of an actuating arrangement in a parking position, and that in the parking position, the sliding piece is adjustable relative to the coupling piece. This results in a simple structure for the feeder and the operation of the feeder can be advantageously integrated into the movement of the drawer. In order to obtain a defined sequence of movements in the operation of the Ausschiebeanordnung, it may be provided that the sliding piece between an on and a Ausschubstellung is adjustable.

For a retraction device according to the invention then results in a simple and inexpensive construction, if it is provided that the Ausschiebeanordnung comprises a spring element, and that the spring element biases the sliding piece in the insertion position. The spring element can transmit its spring energy to the sliding piece upon actuation of the Ausschiebeanordnung in the closed position of the drawer. The drawer is thus brought into the partially open position.

A particularly preferred embodiment of the invention may be characterized in that the Ausschiebeanordnung has a Überhubmechanismus to cancel the insertion position. Thus, the feeder can be handled very user-friendly. To trigger the Ausschiebeanordnung, depending on the design of the drawer, for example, be operated only by pressing the drawer front of Überhubmechanismus.

If it is provided that the Ausschiebeanordnung comprises a carrier, and that in an adjustment of the sliding piece from the Ausschiebstellung into the insertion position, a control, in particular a latch is effective, which allows an adjustment of the sliding piece relative to the carrier, then a triggered Ausschiebeanordnung be easily reloaded.

In order to prevent inadvertent release of the Ausschiebeanordnung is a variant of the invention such that the sliding piece secured in the insertion position by means of a locking piece.

A preferred embodiment variant of the invention is such that a control of the Ausschiebeanordnung when closing the drawer on a body side mounted locking element between adjustment of the Ausschiebeanordnung blocked from the Ausschiebstellung in the insertion position. - A -

A reliable operation of the feeder device is guaranteed by the fact that the control secures the insertion position of the push-out arrangement, at least in some areas caused by the spring adjustment of the coupling piece.

The actuation of the Ausschiebeanordnung succeeds simply by the fact that the control from the feed position for unlocking the Ausschiebeanordnung is adjustable against a holding piece.

The object of the invention is also achieved with a method for operating a drawer or the like, wherein in the closed position of the drawer a Ausschiebeanordnung is triggered, which moves the drawer from the closed position to a partial open position, and then in an adjustment of the drawer the part-opening position is a spring tensioned.

Here again serves the Ausschiebeanordnung for convenient opening of the drawer from the closed position. Then, when the drawer is pulled out of the partial opening position, then this pulling movement is used to tension the spring, which is later relaxed when pulling the drawer into the closed position.

This sequence can be realized particularly comfortable by the fact that during the opening of the drawer from the part-opening position a coupling piece is moved from a retraction position to an extended position, and that brought on reaching the extension position the coupling piece in a parking position and the coupling between the Ausschiebeanordnung and the coupling piece is lifted.

The ease of use is then especially in handle-less drawers, etc. high, if it is provided that an overstroke mechanism is actuated to trigger the Ausschiebeanordnung from the closed position. If it is provided that when a movement of the drawer from an open or partially open position in the direction of the closed position, the Ausschiebeanordnung is brought from its Ausschiebstellung in the insertion position, the Ausschiebeanordnung is brought when closing the drawer in the insertion position, so that this process in The "natural" movement of the drawer is integrated, which is perceived as particularly user-friendly.

For a smooth closing operation, it may be provided that the Ausschiebeanordnung is pulled by the spring in the closed position of the drawer and simultaneously braked by means of a damper.

For tensioning the Ausschiebeanordnung it can be provided that the Ausschiebeanordnung when closing the drawer, etc. is driven with a control on a locking element. This allows a low parts cost.

It is advantageous that the blocking element is moved in the interior of the body on the locking element. As a result, a reliable operation and a protected accommodation of the actuating point is possible. In addition, results for the operator a clear and easily understandable operation.

A variant of the invention is such that the Ausschiebeanordnung immediately before the coupling piece is retracted with the spring is brought from the Ausschiebstellung in the insertion position.

The invention will be explained in more detail below with reference to an embodiment shown in the drawings. Show it:

Figures 1 to 10 a feeder in side view, partly in section and in different operating positions. Figure 1 shows a feeder, as it comes for example in drawers used. Also conceivable is the use in other components to be moved, such as doors, flaps, etc. The retraction device comprises a base part 40 and a housing 10, which is fastened to a housing body (not shown) in each case. Furthermore, a Ausschiebeanordnung 20 is provided, which is arranged on a drawer (also not shown).

The housing 10 is provided with screw 1 1 1.1, with which a corpus-side attachment is possible. The housing 10 has two mutually parallel spaced side walls 1 1, are incorporated in the guides 1 1.2. In this case, the guides 1 1.2 have a slot-shaped opening, which expires in a widened recess 1 1.21. The guides 1 1.2 of the two side walls 11 are aligned with each other.

In the housing 10, a damper 12 is housed. The damper 12 is designed as a fluid damper, in the present case as an air damper. The use of an air damper has the advantage that in the event of damage no liquid can escape and contaminate the drawer contents. The damper 12 has a cylinder 12.6, in which a piston 12.2 outgoing from the insertion position shown in Figure 1 are pulled out. During the return movement of the piston 12.2 he works against an air cushion, the air pressure is continuously reduced. For this purpose, a small opening in an insert 12.3 is provided, through which the compressed air can escape in a controlled manner. At its end facing away from the insert 12.3, the piston rod 12.1 has a head section 12.4, which forms a pivot bearing 12.5. At the pivot bearing 12.5 a coupling piece 13 is pivotally supported in the form of a tilting element. The pivoting movement in this case runs around a pivot axis running perpendicular to the image plane according to FIG. On the coupling piece 13, a spring holder 13.1 is arranged, which holds one end of a spring 14. The other end of the spring 14 is hung on the housing side. The coupling piece 13 has a trigger 13.2, which is arranged at a distance from the pivot axis. Furthermore, a driver 13.4 is present on the coupling piece 13, which is formed via a spring element 13.5 on an arm 13.3. With the driver 13.4, a connecting part 30 of a Ausschiebeanordnung 20 is releasably connectable.

The Ausschiebeanordnung 20 includes the connecting part 30, whose task is to produce the detachable coupling with the coupling piece 13. For this purpose, the connecting part 30 on a holder 32 has a latch 33 which can be coupled in the region between the trigger 13.2 and the driver 13.4. Furthermore, the holder 32 carries by means of a pivot bearing 34, a control 35 in the form of a lever. At its free end facing away from the holder 31, the control 35 is equipped with a rotatable roller 37 and a rotatable blocking roller 38. Between the pivot bearing 34 and the blocking roller 38, a stop 36 is formed. On the holder 32 includes a support 31.

On the carrier 31, a plunger 24 is held at the end facing away from the holder 32 via a threaded connection. For this purpose, the plunger 24 is screwed with an external thread 24.1 in a threaded receptacle of the carrier 31. The plunger 24 carries a locking ring 24.2. This is freely rotatably supported in a bearing receptacle of the plunger 24 in the circumferential direction. The locking ring 24.2 has a latching element which is guided in a control cam 23 of a hollow cylinder of a sliding piece 21. In this case, the control cam 23 is incorporated in the form of a groove in the inner wall of the sliding piece 21. The control cam 23 and the locking ring 24.2 of the plunger 24 form a Überhubmechanismus. The operation is similar to a ballpoint pen, wherein the plunger 24 forms the push button of the ballpoint pen. In the sliding piece 21, a spring element 22 is set in the form of a helical spring and secured against buckling on the walls of the hollow cylinder.

The holder 32 is slidably guided in a linear guide 34.1 with a hinge pin forming the pivot bearing 34. The wall 34.1 forming the linear guide carries a mold 39, which forms a counter surface 39.1 and a tread 39.2. The fitting 40 is U-shaped in cross-section. It has a mounting portion 41 with holes 43 for screwing with a furniture body. At the attachment portion 41, a wall 42 connects perpendicular to. The wall 42, the mounting portion 41 and a parallel to this further wall carry an integrally formed, inclined locking surface 46 and a retaining piece 47. Furthermore, a locking element 44 is pivotally hinged to the mounting portion 41 and by gravity and / or a spring element 22 in the in Fig. 1 shown starting position held. The blocking element 44 has two oppositely oriented control cams 44.1, 44.2.

With reference to Figures 1 to 10, the operation of the feeder device according to the invention will be explained in more detail below.

FIG. 1 shows the starting position of the intake device, that is to say the position in which the drawer is in the closed position. This represents the position in which the coupling piece 13 is in the retracted position. The overstroke mechanism is in a latching position, wherein the latching ring 24.2 is blocked at a latching projection of the control cam 23. The blocking element 35 is held by means of a stop 35.1 on the holder 32 in a raised unlocking position. To release the overstroke mechanism, an overstroke Ü in, for example the drawer front, is introduced in the direction of the actual drawer closing movement. This overstroke Ü is introduced via a sliding piece 21 screwed to the drawer. In this case, the sliding piece 21 shifts a little bit against the bias of the spring element 22 in the direction of the Über Ü over the plunger 24. As a result, the detent position of the locking ring 24.2 lifted in the control cam 23 and the locking ring 24.2 twisted in Umfangsshchtung until it is in a Linear section of the cam 23 passes. In order to carry out the excess lift Ü, the latch 33 is supported on the trigger 13.2. Now, if the depressed drawer is relieved, then the sliding piece 21 is brought from its insertion position (Figure 4) in the Ausschubstellung due to the released locking connection between the locking ring 24.2 and the control cam 23. This adjustment S is effected by the spring element 22, which holds the sliding piece 21 biased in the insertion position.

Figure 2 shows the Ausschubstellung. This movement moves the sliding piece 21 and with it the drawer into a first partial open position (as shown in FIG. 2).

In this adjustment, the holder 32 and with this the carrier 31 remain, and in contrast, the linear guide is 34.1 (in Fig. 1 to the left) moved. The sliding movement S is limited by the stop 36, which abuts against the counter surface 39.1. This position is shown in FIG. 2.

When the position shown in Figure 2 is reached, the drawer can be conveniently gripped and pulled manually in a further part-opening position or fully in the open position. In this case, the coupled with the drawer Ausschiebeanordnung is then moved in the opening direction Ö. Since the coupling piece 13 is coupled to the latch 33 with the Ausschiebeanordnung 20, and the coupling piece 13 in the opening direction Ö (see Fig. 3) is moved. In this case, the coupling piece 13 is guided in the guide 1 1.2. The coupling piece 13 takes the piston rod 12.1 of the damper 11 and thus displaces the piston 12.2. At the same time the spring is stretched. The coupling piece 13 is pulled by the puller 20 until the guided in the guide 1.2 1.2 13.4 driver enters the region of the recess 1 1.21. Due to the eccentric to the pivot axis 12.5 acting spring 14, the coupling piece 12 is tilted about the pivot axis 12.5, wherein the driver 13.4 falls into the recess 1 1.21. In this case, it comes out of engagement with holder 32. Since now the connection between the Ausschiebeanordnung 20 and the coupling piece 13 is repealed, the drawer can be further extended in the freewheel, as Fig. 4 illustrates. In this case, the roller 37 deflects the locking element 44 on its control cam 44.1 and lifts it against the Direction of gravity upwards. The roller 37 passes through the blocking element 44 and the control element 35 leaves the fitting part 40 through the opening 45.

Fig. 4 shows a further part-opening position.

When closing the drawer (closing direction S) and thus at the transition of the feeder of Figure 4 of Figure 5, the roller 37 hits the cam 44.2 of the locked in this direction blocking element 44. There it runs against the direction of gravity until the blocking roller 38 on the Tread 39.2 meets, as shown in FIG. 6. Now, the connecting part 30 can not be pushed further in the closing direction S. The closing movement S now causes the plunger 24 to slide into the sliding piece 21, wherein the spring element 22 is tensioned until the plunger 24 finds its latching position (latching ring 24.2 and control cam 23). Then the Ausschiebeanordnung 20 is stretched again and is in its insertion position. During this process, the blocking roller 38 rolls on the running surface 39.2 until it passes over an edge 39.3 at the end of the running surface 39.2, which transfers it into the counter surface 39.1.

In this case, then pivots, as shown in FIG. 7, due to the further on the locking element 44 running roller 37, the blocking element 35 in its blocking position. In this case, the blocking roller 38 bears against the mating surface 39.1 and blocks inadvertent release of the push-out arrangement from the push-in position.

As shown in Fig. 7, the latch 33 hits immediately after the Ausschiebeanordnung 20 was tensioned on the trigger 13.2 and tilts this about the pivot bearing 12.5. The guide elements 13.2 are excavated from the recess 11.21 and the coupling piece 13 is released. Then the guide elements reach 13.6 in the region of the guide 1 1.2 and the spring 14, the coupling piece 13 pull back into the retraction position. The damper 12 dampens this pull-in movement. With the coupling piece of the bolt 33 is pulled on the driver 13.4 (see Fig. 8). In this case, the drawer is pulled over the sliding piece 21 automatically in the closed position. In this case, FIGS. 8 and 9 In the closed position of the drawer, the control 35 falls due to gravity and / or by spring action in the area below the holding piece 47, as shown in FIG. 10. Fig. 10 is again identical to Fig. 1 and shows the starting position in which the drawer is ready for a new operation.

Usually, the housing 10 and the fitting 40 are attached to the furniture body. However, it is also conceivable to attach these parts to the drawer. Then, the Ausschiebeanordnung 20 is attached to the other furniture component.

The arrangement according to the invention may be arranged laterally in the region of one or both of the drawer walls extending in the direction of the drawer movement. The feed guide can also be part of the drawer slide. It can also be arranged centrally under the drawer bottom. Then, for example, the Ausschiebeanordnung 20 is held on the drawer front below the drawer bottom. The housing 10 is then arranged laterally on the furniture body. The coupling of these components then takes place with the inclusion of a cross member or drawer as a link.
